Core Making

Core Manufacturing at Warner Brothers Foundry Company

Core making is the process of creating inserts that fit inside the casting mold, and it’s one of the most critical components of the sand casting process. These cores are essential for forming parts with complex geometries because they direct the flow of the molten metal. Shapes can include internal cavities, recesses, projections and other features not achievable by a typical casting pattern.

At Warner Brothers Foundry, we boast an NBBI-1 No-Bake Core System from Tinker Omega SINTO, one of the industry’s most flexible, low-volume systems. The NBBI-1 enables us to create precise molds that produce exceptional surface finishes for castings with various sizes, shapes and weights.

How Does Core Making Work?

Although operations can produce cores from various methods, we use a blowing process that injects sand into a core box. The no-bake designation refers to a technique that requires no heat to activate the sand and other materials as they harden to create the core. Warner Brother Foundry uses resin sand to manufacture the cores to ensure they can stand up to the high temperatures of the casting process.

The NBBI-1 utilizes a blow cycle with a tube attached to an existing sand mixer. The system’s blow head lowers and seals the tube to the core box’s blow plate. Compressed air blows the sand into the core box, and the system automatically vents and raises the head after the programmed blow time. At the end of the cycle, the operator clears any excess sand from the tube and removes the core box from the machine.

The NBBI-1’s 48- by 48-inch platform accommodates large horizontally or vertically split core boxes, while the open design optimizes core box loading and unloading. The multiaxis blow head allows flexible positioning and placement of additional boxes for sequential blowing.
